146 CANARIAN COLEOPTERA. 



not so posteriorly-constricted prothorax (which has its basal angles 

 more obtuse, and its hinder central space, between the fovese, both 

 narmiuer and much less elevated, or embossed), will at once serve, 

 apart from the numerical peculiarities of its antennal joints, to dis- 

 tinguish it from the H. cavlarum. As regards this latter character 

 indeed, it would appear that whilst some of the individuals of this 

 species have those organs composed of only nine articulations, others 

 have them made up of ten, — a feature which, in all probability, is a 

 sexual one ; but so singular a fact has occasioned, not unnaturally, 

 some little confusion in the synonymy — the insect having, in con- 

 sequence, been described under several different names. In speci- 

 mens, however, which I have received from the Abbe Stabile of Milan, 

 from Prof. Heer of Zurich, and from the late Mr. Melly of Liverpool 

 (the last tivo sets of which were labelled as types coming from M. 

 Villa, and all of which I believe are specifically identical), there are, 

 in each case, examples falling under both of these categories. In 

 the only Canarian specimen which has as yet come beneath my ob- 

 servation the antennae are 10 -articulate ; which thus far, therefore, 

 a£?rees with (I imagine both sexes of) the B. Kunzei *. Neverthe- 

 less it could not possibly be confounded with that species, since its 

 smaller size, rather narrower outline, and more pubescent surface, 

 combined with its comparatively diminutive eyes and less posteriorly- 

 constricted and less basally-cmbossed prothorax, will suffice to sepa- 

 rate it therefrom. My unique Canarian example was, like that of 

 the H. caularum, captured from under vegetable refuse at Haria, in 

 the north of Lanzarote.

The European C. fulva, remarkable for its pallid hue, coarse 

 pubescence, and rather robust, elongate legs, is apparently scarce in 

 these islands, — where, as in Madeix^a, it has most probably become 



* It is rather curious that all the Hohparameci as yet characterized (four in 

 number) have now been detected in the Atlantic islands, —namely, tlie H. Kunzei 

 at Madeira, the caularmn and singularis at the Canaries, and the niger in both 

 Groups.
